Not as weird as all that though.
I have just brought a storm/lustre machine, se03.esc.qmul.ac.uk into
service at QMUL[1],
AIUI, storm uses ACLs to control file access - so on our cluster,
permissions are:
[root@fe08 storm_3]# ls -al
total 32
drwxr-xr-x 8 root root 4096 May 22 14:54 .
drwxr-xr-x 6 root root 4096 May 15 12:12 ..
drwxrwx---+ 8 205 205 4096 May 30 15:57 atlas
drwxrwx---+ 4 205 205 4096 Jun 1 18:44 cms
drwxrwx---+ 2 205 205 4096 Jun 2 18:25 dteam
drwxr-x--- 2 205 205 4096 May 22 14:54 lhcb
drwxrwx---+ 3 205 205 4096 Jun 2 19:19 ops
drwxr-x--- 2 205 205 4096 May 22 14:54 vo.londongrid.ac.uk
[root@fe08 storm_3]# ls -al atlas/
total 32
drwxrwx---+ 8 205 205 4096 May 30 15:57 .
drwxr-xr-x 8 root root 4096 May 22 14:54 ..
drwxrwx---+ 5 205 205 4096 Jun 1 12:59 atlasdatadisk

Does rfio work at QMUL?
It won't give good performance - AIUI, all rfio traffic goes through the
SE - which only has a single Gbit link to the worker nodes and disk.
